Many organizations and companies provide computing services over a plurality of communication networks. For example, computing services may include web services such as web storage or virtual servers that can be provided over the Internet to different clients. In some instances, virtual servers may be rented out to clients on as needed basis.
Generally, a system may include multiple subsystems to perform various different functions. In most instances, each subsystem may utilize fixed computing and I/O resources to perform the intended function. Thus, I/O bandwidth of each subsystem may be limited by the allocated I/O resources. Hence, each subsystem may be limited to providing a level of performance based on the assigned computing and I/O resources.
